COP-SPRING FOR LOOM-SHUTTLES.

SPECIFICATION forming part of Letters Patent No. 459,849, dated September 22, 1891.

Application filed June 16, 1891. Serial No. 396,480. (No model.)

To ctZZ whom it may concern.-

Be it known that I, FRANK A. WILMOT, a citizen of theUnited States,residing at Bridgeport, in the county of Fairfield and State of 5 Connecticut, have invented certain new and useful Improvements in Cop Springs for Loom-Shuttles; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable oth- IO ers skilled in the art to which it appertains to make and use the same.

My invention relatesto the class of shuttle-springs described and claimed in patent to Sidney S. Edwards, No. 394,915, dated December 18, 1888, under which patent the VVilmot dz Hobbs Manufacturing Company, of

Bridgeport, Connecticut, are sole licensees.

The special object of my presentinvention is to provide oil-holes at the opposite ends of the spring, which will distribute the oil on the spindle-head at the point of greatest wear and will at the same time prevent the spatteringof oil upon the cloth when the shuttle is again first put in rapid mot-ion in the loom. Heretofore in using this class of springs the only way to oil the spindle-headv has been to hold the end of the spindle downward and drop oil in from above between the spindlehead and the spring, the result being that serious damage has quite frequently been done to the cop, and more especially to the cloth, by the spattering of oil from under the spring, owing to the rapid motion of the shuttle in the loom. I wholly overcome this objection in the manner whichI will now describe, re ferring by numerals to the accompanying drawings, forming part of this specification, in which Figure 1 is a plan view of one end of a copshuttle provided with my novel shuttle spring; Fig. 2, a longitudinal section show- 'ing the cop in operative position; and Fig. 3 is a similar section showing the spindle-head tilted, as when removing or inserting a new 1 denotes the body of the shuttle; 2, the spindle; 3, the spindle-head; 4, the cop; 5,

the spring, and 6 the screw by which the spring is held in place. The spring is pro-- vided at each end, in order to make it reversible, with a lug 7, which serves as a stop for the spindle-head to prevent the cop-tube from coming in contact with the end of the spring when the spindle is raised. This lug broadly constitutes the subject-matter of the Edwards patent referred to, the sole assignees of my present invention being the sole licensees under the said Edwards patent.

The essential feature of my invention is that I form the lugs by striking in the metal of the spring itself, the outerends of the lugs being detached from the body of the spring, leaving the inner ends attached thereto, as clearly shown in Figs. 2 and 3. This 0011- struction is valuable for the reason that the springs can be made more cheaply and the lugs are found to work more satisfactorily in use. The special advantage of my improved construction is, however, that I provide an oil-hole which permits a drop of oil to be placed upon the bearing portion of the spindle, but back from the outer edge of the spindlehead, so as to avoid the danger of spatterin g oil when the spindle is in rapid motion in the loom. My improved construction has been thoroughly tested in practice and is found to accomplish perfectly the result had in view.

Having thus described my invention, I claim A cop-shuttle spring having a lug adapted to serve as a stop for the spindle-head, said lug being formed by striking in the metal, leaving one end attached, thereby forming an oil-hole through the spring, so that the bear ing of the spindle-head may be oiled without danger of spattering oil when the shuttle is in motion.

In testimony whereof I affix my signature in presence of two witnesses.

FRANK A. IVILMOT.
